TMS570LC4357: ePWM module for clock generation

Part Number: TMS570LC4357


Hi,

We are using ePWM module to generate a clock signal of 768kHz and 878kHz.

But, due to internal divider value limitations of microcontroller, we are unable to get exact values of  768kHz and 878kHz.  We are getting around 769kHz or 873.78KHz.

Is there any other way, the exact clock frequencies can be generated?

Also, please let us know the formula, that determines the exact clock frequency output based on divider value.

Regards,
